Fou à pieds bleus Sula nebouxii

Large seabird of inshore waters, often seen from beaches but not usually up close. Adult has streaky brown-and-white neck and bright blue feet. Immature has dusky brownish head and neck and grayish feet. All plumages told from Brown Booby by white at the base and tip of the tail. Typically flies and soars fairly high up. Feeds by spectacular, steep-angle plunge-dives. Breeds locally in colonies on offshore islands, nesting on the ground. Most well-known from the Galapagos but occurs extensively along the Pacific coast of Middle and South America, especially in the Gulf of California.
